Methods for Collection and Evaluation of Concrete Data within the Nuclear Industry

| 2024:1032 | Felix Kåhrström, Judith Hambraeus, Mårten Janz, Per Johannesson, Afry
This project has identified variations in the level of digitalization across the nuclear facilities as well as differences in data storage and analysis methods.

\u003Cp\u003EThe Swedish and Finnish nuclear facilities need methods to analyse data from measurements and visual inspection. Currently, data exist in several locations but is often stored in reports. An important first step is to establish an ETL process to extract, transform and load the data into a data repository to facilitate the analysis. Various statistical methods can then be used to analyse the data to make trends and predictions, such as regression analysis. To analyse future data from visual inspections and improve data collection, the recommendation is to use a software available on the market, which often includes 3D models and facilitates documentation through a tablet. Implementing BIM and 3D modelling could also be a viable solution.\u003C/p\u003E

    Inspection of Pipes in Leak Indication Systems

    Leak indication systems can detect leakage from fuel pools early. These systems consist of long systems of pipes with very small diameters, which can lead to blockages which is very important to prevent. but finding methods for this is difficult due to the geometrical complexity. Therefore, this study examined possible methods for detecting and removing mineral blockages in narrow, embedded leak indication pipes with sharp bends.

    Syntesrapport 2007-2024: Betongtekniskt program kärnkraft

    Energiforsk driver sedan 2007 ett forskningsprogram kring betongkonstruktioner inom kärnkraftverken. Det finns ett behov av att bygga både kompetens och att utveckla teknikbasen för teknisk förvaltning av byggnader och konstruktioner inom kärnkraftindustrin.

    Testing of acoustic cameras to detect leakage through a concrete structure

    The purpose of the project was to see how well the acoustic cameras worked on a concrete containment with known leakage through the structure.
